ARG82801KLVATR

Overview

The ARG82801KLVATR is a specialized PMIC designed for safety-related systems, certified to AEC-Q100 and ASIL-D standards. It features nine outputs: one buck or buck-boost pre-regulator, four internal LDOs, and four gate drivers. Operating from a 3.8V to 36V supply, it includes a 2.2MHz switching frequency. The device is housed in a 38-eTSSOP package with an exposed pad, supporting junction temperatures up to 150°C.

Feature Summary

• ASIL-D certified power management IC for safety-critical applications
• Integrated buck/buck-boost pre-regulator with four LDOs and four gate drivers
• Supports SPI interface for configuration and monitoring

Applications

• Automotive safety-related systems
• Advanced driver assistance systems (ADAS)
• Vehicle control units requiring high reliability

Procurement Notes

Verify the specific suffix KLVATR against official Allegro MicroSystems documentation to confirm pinout, thermal characteristics, and functional equivalence. Ensure the procurement source provides valid traceability and authenticity certificates for automotive-grade components. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit risks.

Selection Notes

Select this component when designing systems requiring ASIL-D compliance and integrated power sequencing. The combination of switching regulation and linear outputs reduces external component count. Verify that the input voltage range of 3.8V to 36V matches the system bus requirements. Confirm that the 38-pin eTSSOP package fits the PCB layout constraints and thermal dissipation needs.
